, -minates in a solid projection, 4, having e t lznown 1315,11,,-PETIERIQLITSGI'B a it shoulders, o and 6, formed integrally there- T, is secured to the eccentric strap projece tion, a, clamping bolts, 8, extending therea The con- Stl'llCtXOIl or the eccentric and the attaching of the rigid end piece thereto is the usual form of construction for which I do not 1 claim any invention.

I provide two resilient connecting pieces, 9 and, 10, which are provided at each end with apertures located ina staggered rela tion to each other in order that the connect ng pieces may not be weakened, which would necessarily be the result if the aper tures were formed in straight lines. The inner surface of each of the connecting pieces,

9 and 10, I provide with angular shaped grooves, 11,!extending entirely across the width of the connecting strap, upon their inner end surface, and a similar groove is formed inthe outer surface of the rigid piece, 7, and also in the portion of the shaft, 12, which is connected at its opposite end to a shaker not shown in the drawing. The connecting piecesfl and 10, are connected at each end to the rigid portions, 7 and 12', of

the shaft, with their convex surfaces adjacent to each other in the central portion but not close enough so that their surfaces may contact. Theelamp bolts, 12 and 13. are inserted at each end through the apertures in the connecting pieces, and the rigid portions of the shaft, 7 and 12. Between the under end surfaces of the rigid pieces and the resilient connections I insert-pieces of iron, 14, approximately rectangular in shape,

, which are adapted to seat in the grooves,

1 1, f0rn1ed in the inner surface of the resihent connections and rigid portions of the n a shaft, and extend transversely the full width escribingwmy]invention indetail, refratepieoes connecting the two rigid portions of the shaker arrn allows sufficient, flexibility to overcorneany lost motion and the tendency of theueccentric strap to jar, thus causing a looseninglof the boltsat the eccentric and shaker ends of the arms; and

parts, and it is noted also to prevent the snapping off of the arm,-

' from the scope of my'invention.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is: g

In a flexible shaker arm, rigid end pieces provided with angular shaped grooves, curved connecting pieces provided with transverse angular grooves adapted to register with the angular grooves in the rigid end pieces, said connecting pieces having their convex surfaces adjacent to each other in the central portion thereof, meansfor securing said connecting pieces to said rigid pieces, and aserieszot' adapted to be inserted in the apertures formed by the registering of tlie transverse angular grooves in the endpieces and connecting pieces; substantially as described.
